Systemic lupus erythematosus (SLE) is a common autoimmune connective tissue disease with unclear etiology and pathogenesis. Mesenchymal stem cell (MSC) and MSC derived extracellular vesicles (EVs) play important roles in regulating innate and adaptive immunity, which are involved in many physiological and pathological processes and contribute to the immune homeostasis in SLE. The effects of MSCs and EVs on SLE have been drawing more and more attention during the past few years. This article reviews the immunomodulatory effects and underlying mechanisms of MSC/MSC-EVs in SLE, which provides novel insight into understanding SLE pathogenesis and guiding the biological therapy.

Background: The COVID-19 pandemic contributes to the burden of living with different diseases, including Systemic Lupus Erythematosus (SLE). We described, from a narrative point of view, the experiences and perspectives of Italian SLE adults during the COVID-19 emergency, by distinguishing the illness experience before and after the lockdown. Methods: Fifteen patients were invited to participate. Illness narratives were collected between 22 and 29 March 2020 using a written modality to capture patients’ perspectives before and after the COVID-19 lockdown. We performed a two-fold analysis of collected data by distinguishing three narrative types and a qualitative analysis of content to identify the relevant themes and sub-themes reported. Results: Eight narratives included in the final analysis (mean length 436.9 words) have been written by eight females (mean age 43.3 ± 9.9 years, mean disease duration 13.1 ± 7.4 years). Six patients provided a quest narrative, one a chaos and the remaining one a restitution narrative. By text content analysis, we identified specific themes, temporally distinct before and after the lockdown. Before COVID-19, all the patients referred to a good control of disease, however the unexpected arrival of the COVID-19 emergency broke a balance, and patients perceived the loss of health status control, with anxiety and stress. Conclusions: We provided unique insight into the experiences of people with SLE at the time of COVID-19, underlining the perspective of patients in relation to the pandemic.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease with multiorgan involvement and high mortality, which was reduced because of the most widely and classically used immunosuppressive therapies. However, some patients continue to have significant mortality. So a shift in the approach to the treatment of SLE is needed. In the past decade, most transplants have been performed in the treatment of SLE with allogeneic or autologous hematopoietic stem cells and currently emerging mesenchymal stem cells. There are some important differences between the two procedures.

Extracellular vesicles (EV) are microparticles released in biological fluids by different cell types, both in physiological and pathological conditions. Owing to their ability to carry and transfer biomolecules, EV are mediators of cell-to-cell communication and are involved in the pathogenesis of several diseases. The ability of EV to modulate the immune system, the coagulation cascade, the angiogenetic process, and to drive endothelial dysfunction plays a crucial role in the pathophysiology of both autoimmune and renal diseases. Recent studies have demonstrated the involvement of EV in the control of renal homeostasis by acting as intercellular signaling molecules, mediators of inflammation and tissue regeneration. Moreover, circulating EV and urinary EV secreted by renal cells have been investigated as potential early biomarkers of renal injury. In the present review, we discuss the recent findings on the involvement of EV in autoimmunity and in renal intercellular communication. We focused on EV-mediated interaction between the immune system and the kidney in autoimmune diseases displaying common renal damage, such as antiphospholipid syndrome, systemic lupus erythematosus, thrombotic microangiopathy, and vasculitis. Although further studies are needed to extend our knowledge on EV in renal pathology, a deeper investigation of the impact of EV in kidney autoimmune diseases may also provide insight into renal biological processes. Furthermore, EV may represent promising biomarkers of renal diseases with potential future applications as diagnostic and therapeutic tools.

Hydroxychloroquine (HCQ) and its related drug, chloroquine, have been under use for malaria for the past 75 years. Its use for malaria, rheumatoid arthritis and systemic lupus erythematosus are Food and Drug Administration (FDA) approved. These drugs have immunomodulatory and antiviral actions. More and more indications for this drug are being explored. These drugs are still under study as possible treatments for coronavirus disease 2019 but at present FDA has revoked its emergency use authorization for these two drugs. However, in many other indications, HCQ is a valuable drug but monitoring for adverse effects is mandatory.

Systemic lupus erythematosus (SLE) is a chronic inflammatory multisystem autoimmune disease. Ascites when associated with pleural effusion and raised CA-125 levels in SLE patient, is known as pseudo-pseudo Meigs’ syndrome (PPMS). This is the case of a 22-year-old lady who presented with complaints of abdominal distension for one month and had a history of spontaneous abortion in the past. Abdominal imaging did not reveal any tumor and after extensive workup a diagnosis of PPMS was made. She was successfully treated with steroids, hydroxychloroquine and cyclophosphamide.

Background: The progression of systemic lupus erythematosus (SLE) leads to anemia in patients, adversely affecting prognosis. The diverse causes of anemia may include excessive eryptosis or premature suicidal erythrocyte death characterized by cell shrinkage and phosphatidylserine (PS) exposure on the cell surface. The present study explored if SLE enhances eryptosis and the underlying mechanisms. Materials and Methods: Eryptosis was assessed using flow cytometry in healthy volunteers (n = 20) and anemic patients hospitalized for SLE (n = 22), for parameters including PS exposure, cell volume, cytosolic calcium ion (Ca2+) levels and reactive oxygen species (ROS) and ceramide abundance. These indicators were measured in erythrocytes of experimental subjects and erythrocytes treated with plasma from healthy volunteers or SLE patients. Results: The hemoglobin and hematocrit levels were significantly lower in anemic SLE patients than in healthy volunteers (***p<0.001, p<0.001, respectively). The percentage of PS-exposing erythrocytes was significantly higher in SLE patients than in healthy volunteers (p<0.001), accompanied by an increase in cytosolic Ca2+ levels, oxidative stress. The measurements of PS and Ca2+ levels were significantly higher in the erythrocytes of healthy volunteers following incubation in plasma of SLE patients than in plasma of healthy volunteers for 24h (***p<0.001, *p<0.05 respectively). Conclusion: Eryptosis is enhanced in SLE and may contribute to anemia. The probable underlying mechanisms may be an excessive formation of ROS in erythrocytes. Also, some plasma components may trigger eryptosis by increasing the cytosolic Ca2+ concentration.

Systemic lupus erythematosus (SLE) is a spectrum of autoimmune disorders characterized by continuous inflammation and the production of autoantibodies. Monocytes, as precursors of dendritic cells and macrophages, are involved in the pathogenesis of SLE, particularly in the inflammatory reactions. Previous studies have proved that Pam3CSK4, as a synthetic ligand of TLR2, could stimulate monocytes to differentiated into a M2-like phenotype which presented immunosuppressive functions. However, the underlying mechanisms remain to be further studied. Here, we reported an increased expression of PPAR-γ in the CD14+ monocytes from SLE patients, particularly in the treated group of SLE patients and the group with positive anti-dsDNA antibodies. Additionally, PPAR-γ expression decreased in the SLE patients with skin lesion. Furthermore, we demonstrated that Pam3CSK4 stimulation can decrease the expression of CCR7, CD80, IL-1β, IL-6, IL-12, and NF-κB which were related to the M1-like subset of monocytes and increased the expression of ARG1 which was related to the M2-like subset through upregulated PPAR-γ expression and consequently downregulated NF-κB expression in the CD14+ monocytes in a time-dependent manner. ChIP-qPCR results further demonstrated that Pam3CSK4 pretreatment could modulate PPAR-γ expression by regulating histone modification through the inhibition of Sirt1 binding to the PPAR-γ promoter. Taken together, our study indicated a protective role of TLR2/Sirt1/PPAR-γ pathway in the pathogenesis of SLE which provided potential therapeutic strategies.

Back Ground: Depression is a natural disturbance of feeling that is characterized by feelings of sadness, loss of interest and easily tired. Steroids are drugs that can reduce swelling, pain and heat due to inflammation through reducing the immune response. Steroids are often used in cases of systemic Lupus Erythematosus in the long term. Therefore management of the disease must be done well because steroids can cause depression. Case Report:Women, 37 years old, depressed mood, disappointment in life, loss of enthusiasm, fatigue, decreased appetite and difficulty sleeping for 1 year. 4 years ago I took steroids for 2 years at a dose of 20mg / day, because rheumatoid arthritis was stopped by os, and for the past 1 year, steroid consumption was due to Systemic Lupus Erythematosus around 60 mg / day. . Before the os consumes steroids, the OS has never experienced depression.BP: 110/70 mmHg , HR 88x/menit, RR 20x/menit, Temp 37°C. Skor BDI 21.
